The pair confirmed the split on Tuesday.

Frost and Mielczarek confirmed their split to News Corp on Tuesday morning. The pair found love on set of the Channel Ten reality TV show The Bachelorette in 2015.

The 2Day FM host and tradesman released a statement through their shared manager Georgina Harrop. It said the pair "just come to the realisation that the best way forward is to separate".

Sam Frost and Sasha Mielczarek met on the set of The Bachelorette Australia.

"They wholeheartedly respect and cherish the friendship they have for one another, which will continue moving forward," the statement read.

"They wish to thank everyone for their love and support over the past 18 months."

The couple broke up before Christmas, according to reports, and Mielczarek has taken to Instagram in a classic millennial post-break up move. He confirms the decision was mutual and stated his love and respect for Frost.

This announcement follows a Instagram post by Sam Frost on Boxing Day, only 24 hours before the announcement of the split. Fans are claiming the post with the caption "Christmas isn't always sunshine" was a precursor to the announcement.
